AC Power & Down Time: Whenever the DX7s will not be used for an extended period of time, it is best to protect it from potential disaster. Electrical storms and other natural or man-made disasters can give rise to power surges, which may damage the digital circuitry of your DX7s - even if the power is turned off. Either unplug your instrument when not in use, or invest in power strips with surge protectors to safeguard all of your electronic equipment. Service & Your Warranty: The DX7s contains no user-serviceable parts. Opening it up or tampering with it in any way will void the warranty, and may also lead you to experience some nasty electrical shocks. If you have a problem with your instrument, please take it to an authorized Yamaha service center. Modifications & Your Warranty: Unless you are assured to the contrary in writing, you should assume that any modifications made to your DX7s will void the original product warranty. Therefore, you should make sure that you receive a warranty (or some other kind of guarantee) from the person or company that is responsible for the modification.
